Group 1 - The core research reveals the key molecular mechanism of maize in coordinating stress adaptation and nutrient utilization, focusing on the role of the protein NLA in low-temperature response and phosphorus absorption regulation [1][3] - The research team developed a new variant of NLA that acts as a molecular hub, integrating cold and phosphorus regulation, which enhances maize cold resistance while suppressing root phosphorus absorption [3] - This achievement provides a new theoretical framework and technical pathway for crop improvement, moving from optimizing single traits to systematic environmental adaptation design, with potential applications in enhancing the efficient use of other key soil nutrients like nitrogen [3] Group 2 - The study utilized artificial intelligence-assisted protein design and gene editing technologies to create a new maize germplasm that combines strong cold resistance and high phosphorus utilization efficiency, contributing to stable and increased grain production [3] - The findings were published in the international academic journal "Nature," highlighting the significance of the research in addressing challenges posed by climate change and multiple stress environments for crop varieties [1][3]
